Mark has been in the tech industry since 2004 when he wrote a regular eBay column for AuctionBytes (now renamed eCommerceBytes). He also contributed articles to the now-defunct Bookologist, Google Tutor, and a few other sites now lost to time (although you could probably find them on the Wayback Machine). Then came a couple of years of English teaching work before MakeUseOf appointed him managing editor in 2007. He remained in that position until 2013.
From 2013 to 2016, he remained at MakeUseOf as a senior contributor, but then branched out into other clients and other areas of writing expertise. He become an expert in cyber-technology and online privacy, online marketing, and online business. He was the Content Management Director for Quiet Light Brokerage, and a contributing writer to outlets such as Lifehacker, NowSourcing, GroovyPost, Lifewire, Trendblog, Small Business Trends, PC World, Online Tech Tips (managing editor), Help Desk Geek (managing editor), Switching to Mac (managing editor), and XDA. He is now a writer and how-to editor for Android Authority.
In 2017, Mark started self-publishing his own spy fiction novels. He has received rave reviews for his Department 89 series and Scorpion series. He now has 17 books out.
